Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

In this activity, learners explore nonrenewable resources and learn why these resources are finite.

This display shows slow chemical reactions in colorful crystal formations known as Liesegang Rings. These reactions are similar to those forming the rings in agates.

In this activity, learners will build rainwater collectors to practice meteorology in their own backyard. Collect and analyze data to determine how much rainfall you get in a set period of time.

In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

In this data activity, learners will explore shipwrecks from four National Marine Sanctuaries on the West Coast of the United States.

In this activity, learners use tsunami time travel maps to predict how long it will take a tsunami to reach the shore.

This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this online activity, learners discover how random variation influences biological evolution.

The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

This chocolate chip cookie recipe includes templates for baking night sky constellations of the season right on top! Two templates are included, one for 9pm mid-April, and one for 10pm mid-July.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

Some bugs can walk on the surface of a lake, stream, river, pond or ocean.

This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

The Sacred Cenote at Chichén Itzá is a sink hole, or well, containing groundwater. In this activity, learners create their own cenote using chalk, limestone, acids, and rain water.
